[FFE] mesa 10.3

updating mesa allows us to demote llvm 3.4, so +1 from me on this

How can I test this?

Got it in ppa:canonical-x/x-staging

+1 from me, please also pull http://lists.freedesktop.org/archives/mesa-dev/2014-August/064711.html if you haven't already.

Might want to wait on Riddell's okay, if he has time to test, but if not, I wouldn't block on it either, as you did some basic KDE testing yourself.

I'm against this I'm afraid, we have a history of these late mesa updates causing problems. We can't adequately test it in both KWin 4 and KWin 5 on all the graphics cards in the time left before the release. Upstream says he has not tested mesa 10.3 and won't be able to fix problems in KWin 4.

Testing it just now some problems have occured which I can't definately say are due to the update but I haven't seem them before. Windows stopped accepting keys when I did the dist-upgrade to the new packages. After a reboot the Window Manager Settings -> Desktop Effects dialog appears frozen when I interact with it. I started dolphin and it didn't accept mouse input or allow me to resize it. More testing is needed.

I was tempted to suggest that if someone volunteered to deal with the kwin
issues, it'd be OK, but given the problems you've had, I think it's just too
late in the cycle.

Rescinding my +1 unless the above can get heavier testing on a few different cards, as per IRC.

09:25 < Riddell> I've made a testing matrix, will try to fill it in during beta 2 tests today and tomorrow

Which intel driver is meant in the spreadsheet?

No idea, but it seems those bugs are probably just bugs in kde5, since I don't hit them with 10.3 on amd64/i386, but I can reproduce something similar with the kde5 ppa, without updating mesa.

I tested today with Plasma 4 and Plasma 5 images and the problems I found seem to be unrelated to the mesa update. I also tested on a machine with Plasma 4 and AMD hardware and the mesa update also seemed to go smooth. I'd still rather this did not happen due to unforseen issues we've had from similar updates in the past but I won't block it, +0

Since kwin upstream has told us they won't support kwin4 with mesa 10.3, is
there anyone who could fix problems if they occur after this lands?

Depending on the problems I might be able to fix them myself. I would also like to note that at least with nouveau I haven't encountered any yet.

I've done some more testing just in case, and it looks like there are no regressions on llvmpipe on 32-bits or 64-bits, only new tests passing.

I've also done a comparison of 32-bits llvmpipe against 64-bits, and it looks like there's probably a small issue on the teximage-colors with GL_UNSIGNED_INT. This is not a regression though, it was already the case in 10.2.6.

This broke autopkgtests of some packages; see bug #1374131.

This is likely to be removed from utopic-proposed for now to allow other packages to keep transitioning to utopic.

Doesn't this pretty well establish there's undue risk with going forward with
10.3 this late in the cycle? Also, I don't see where the FFe was approved, so
I'm not sure why this got uploaded?

Hey,

It is my opinion the autopkgtests themselves were broken, but I've added explicit depends in mesa to always force libgl1-mesa-dri to be installed when libgl1-mesa-dri, libegl1-mesa or libgbm1 are installed.

This allows the tests to run correctly again, and presumably fixes the armhf tests too.
